Evidence Level
Tributyrin is a delivery form of butyrate, a short-chain fatty acid that plays a critical role in gut health. Canani et al. (2011) established that butyrate supports intestinal barrier function and modulates immune responses in the colon. Liu et al. (2018) demonstrated that butyrate supplementation can restore gut barrier integrity and reduce markers of intestinal permeability in both animal and human models. Tributyrin is specifically designed to address the poor colonic bioavailability of free butyrate salts.
Recent studies highlight the benefits of tributyrin supplementation across various applications. Coelho et al. (2025) conducted a randomized controlled study with 148 gestating sows, finding that tributyrin supplementation reduced stillbirths by 35% and increased litter weight at birth by 10%. Dang et al. (2023) reported improved growth performance, nutrient digestibility, jejunal villus height, and fecal microbiota in a study with 150 weaned pigs supplemented with tributyrin and anise mixture. Additionally, van Deuren et al. (2022) demonstrated that Akovita SCT, enriched with butyrate and hexanoate triglycerides, increased postprandial systemic butyrate and hexanoate levels in men with overweight/obesity compared to placebo.
Mocanu et al. (2021) explored the effects of tributyrin supplementation in mice following ileocecal resection, finding that it enhances gut microbial recolonization and reduces gastrointestinal inflammation. These findings underscore the potential benefits of tributyrin across diverse applications, from animal husbandry to human health.
